Hi Dale,
I'm sure you are ahead of me, but just in case:
Skysolve didn't immediately work when I installed the newcamlib version on the standard 64bit Raspberry Pi OS (non-legacy). I had to install the cv2 python library manually with sudo apt install python3-opencv . After that everything worked great with my Raspberry Pi 4 and HQ Camera.
Any chance we could get a button in the web interface to shutdown? Would be nice to not have to have the switch since autohotspot seems to work well.
